Abstract

The invention discloses a liquid cooling system of a power battery pack. The liquid cooling system comprises a frame and a radiating component, the radiating component is arranged in the frame in an embedded manner and comprises a plurality of liquid cooling plates and a plurality of liquid cooling pipelines arranged on the liquid cooling plates, the liquid cooling pipelines are combined by S-shaped pipelines and straight pipelines and are connected serially and parallelly. The liquid cooling system is small in temperature difference of cooling liquids in the liquid cooling pipelines, small inpressure loss of the liquid cooling pipelines, simple in structure, light in weight, strong in heat exchange, excellent in temperature equalization, low in cost, short in developing period and worthof being popularized.

Description

technical field [0001] The invention relates to the technical field of electronic heat management, in particular to a liquid cooling system for a power battery pack. Background technique [0002] With the rapid development of electric vehicles, the issue of thermal safety of power batteries has become increasingly prominent. The normal operating temperature range of the battery is 15-40°C. If the temperature is too high, it will affect the service life and safety of the battery; if the temperature is too low, it will affect the performance and cruising range of the battery. Therefore, in order to ensure the normal operation of the battery, effective thermal management of the battery is urgently needed. That is, in a low temperature environment, the battery is heated to a certain temperature to start the battery operation; in a high temperature environment, the battery is cooled to the normal operating temperature range to ensure the thermal safety of the battery.
